In France June5,1941 l 3 claims. (o1. 25o-55) My invention relates toadjustable tables such as those for surgical purposes, those used asdrawing boards, etc. and it refers more particularly to tables forsurgeons operating with the aid ol X-rays.

My invention has for its object to provide a table of the kindabove-referred to which will be more easily adjustable and thus moreconvenient in use than the known tables.

It is a further object of the invention to provide a table for surgicaland the like purposes for use with an X-ray tube device, in which thetable has a single supporting column carrying a substantially flat trackon which is movably mounted a body support for cycloidal movement on thetrack. On the under side of the body support there is movably carried asupport for the X-ray tube device, and the mounting of thel body supporton the column for cycloidal movement on the track is positioned anddimensioned to preof the main parts when the table is oscillated aboutits transverse axis.

Figs. 7, 8 and 9 refer to the electrical equipment of the table which isshown in end view, plan view and partial view to an enlarged scale,respectively.

Fig, 10 is a perspective View showing a lateral abutment.

Fig, l1 shows the stretcher, the "arching device and the shafts whichmay be associated therewith.

Figs. 12 and 13 are respectively a perspective view and a plan View ofan X-ray bulb support adapted to be associated with the table.

The table shown in the drawings comprises a base I supported by means ofcastor wheels, the said base being provided with a telescopic column 2-associated with a gearing to operate same in order to vary its height.

The table proper 3 is supported by column 2 through a mechanism adaptedto permit its'- adanism comprising a pair of horizontal racks 4 and` Igilxed to side members 5d and 5g connected by a transverse member 5, anda pair of toothed sectors 6 and 6g cooperating with said racks. Members5, 5d and 5g form a rigid structure iixed to column 2, while sectors Band 6g are rigidly carried by the longitudinal members 'Id and 'Ig of aframe 1 which carries the table proper 3, as it will be explained below.

Carriages 8 and 8g are adapted to slide longitudinally along the upperpart of side members 5d andg and they are actuated by a pair oflongitudinal screws 9 and Sg horizontally and pivotally carried by theend portions 5t and 5p of members 5d and 5g. They are provided withtrunnions on which sectors 6 and 6g are pivoted.

- Fig. 6 clearly demonstrates the operation of the gearing described.

When screws 9 and 9g are actuated in unison (which is obtained by anyappropriate means, such as chains and sprockets) carriages 8 and 8g aremoved longitudinally and sectors 6 and 6g are oscillated together withframe 'I to which they are rigidly lixed. The assembly comprising theX-ray bulb and associated parts, carried by frame 7, thus assumespositions such as shown at IGA, IIIB and IIIC and is tangent to acylindrical geometrical surface XY, the section of which is a eycloid.It will easily be grasped that this is an advantage with respect to themere pivoting of frame 'I about a lixed transverse axis, as is the knownconstructions; more particularly my invention provides ample space forthe X-ray bulb for any position of the table and avoids any risk ofbreakage of the same against the supporting column 2.

Y Frame 'I supports two columns I I and Ilp respectively lixed to itsrear and front transverse members 'It and 1p, said columns pivotallycarrying the rear and front transverse members 3i and 3p of the frame 3forming the table proper. Two rods I2 and I2p are articulated at theirupper ends to one of the ends of members St and 3p while their lowerends are pivotally connected with carriages I3 and I3p forming nuts ontransverse screws I4 and Mp respectively. It will be understood that byoperating screws Ill and Mp in unison by appropriate means, table 3 maybe pivoted at will about a longitudinal axis.

As shown in Figs. 7 to 9, column 2 may be operated by, an electric motorI5 housed within base I, this motor being electrically connected througha plug |50 (Fig. 3) with a pair of pedals |51 and I5Z (Fig. 1) disposedon a separate base or switchboard I6 and corresponding to upward anddownward movement of column 2. There is also provided a. switch with anoperating head |510 connected by a chain |520 with member and adapted tobe actuated when the table reaches respectively its lowerrnost and itsuppermost positions to cause stoppage of motor I5 while permitting itsrotation in the reverse direction.

The mechanical connection between motor I5 and column 2 comprises aclutch 2 and a shaft with a square and |500 projecting from the gearcase and adapted to receive an actuating handle, in order to permit handactuation when the motor is de-clutched. l

A second electric motor I1 is provided to actuate screws il and 9g; itis energized through a plug |10 to which it is connectedby means ofWires passed through an `articulated tubing I8. Plug |10 is itselfconnected with pedals I11 and I12 on base I6. And there is also provideda pair of end switches |110 and I 1,20 to cause motor stoppage at theends of the stroke.

In Fig. 7 it will befseen that motor I1 drives a, shaft ld extendinghorizontally along one sideof the structure, said shaft being chainconnected with another shaft |1g extending along the other side, andshafts Id and |`lg driving screws 9 and Sy by means of chains andsprockets. Hand actuation is enabled by a square end i100 in cooperationwith a clutch not illustrated.

A third electric motor IS is disposed within a casing 'i0' on member ltof frame 1;",it is controlled through a plug I90byl pedalsflill and |32on base ldassociated with end switches IQN and |920; The gearing betweenmotor I9 and screws I4 and lllpcomprises a pair of gears connecting saidscre'ws'with an actuating shaft ld carried along member ld. Shaft Illdisconnected with motor i9 by means of a slidable pinion I 93 forming aclutch and there is provided a square i900 to vpermit hand actuation.

The support l0 of the X-ray bulb is slidably iik-edV on the transversesides and 20t of a frame, the longitudinal sides 20d and 28g =of whichkare slidable along members vlol and 1g. The side member 20g is providedwith two superimposed longitudinal bores; the rst one, which isthreaded, is adapted to receive a screw. 2| plvotally supported by frame1; and the second one -which is cylindrical, slidably receives a squareshaft 22 also pivotally carried by frame 1. There provided a chain.lsprocket 22g on shaft E2 and another chain sprocket 22d loose on a:Sournal carried by the other longitudinal.

sideV 25d, and sprockets 222g` and 22d ,are connected with cach other bymeans of a chain fixed to pin i60 carried by the correspondingtransverse side of support IB.

, Itwill be understood that the X-ray bulb ma thus be movedlongitudinally by actuating screw 2l. and transversely by actuatingshaft' 22.

squareY ends 2.!0 and 220, or electrically, by means of additional framefreely carried by the meansof the kind described with reference'to"Figs. 7 to 9.

yThe arching device comprises a pairpof rec-v pairs of slides 25, whichare mounted respectively;

on the right and left transverse members of frame 3 or, preferably asshown, on the transverse-megu-V This actuation may b'e performed byhand, throughVV such means comprising bers 26d and 25g of an additionalframe freely carried by the former and adapted to be used as a stretcherfor carrying the patient, by means of sockets 2B provided in the anglesof the said additional frame to receive gudgeons 21 projecting upwardlyfrom the `carrier shafts 21d and 21g (Fig. l1). Slides 25 are providedwith inwardly projecting edges having on their upper face a series ofnotches adapted to receive the transverse pins of wings 24 respectively.

Means are also provided to move the slides of each pair towards those ofthe other pair, preferably a pair of screws 28d and 28g pivotallycarried by the additional frame 26 in parallel relation with respect tothe longitudinal members thereof, such screws being provided withopposed pitches in such a manner that by rotating same the two pairs ofslides may be moved in opposed direction. Screws 23d and 28g are driveneither by hand, through a square endv 28, or electrically by means suchas described with reference to Figs. '1 t0 9.

The table described also comprises a head support 29 and a foot support29p, each being carried by breaches driven through the tubular ends ofthe longitudinal members of frame v3 and iixed at the appropriateposition by means such as radial pins.

Fig. lo'shows an adjustable abutment comprising a split collar 3Dslidably keyed on transverse member 3g (or 3d) and clamped in positionby means of a screw 301, a double plain collar 3| formed of two elementsbetween which collar 3|] is positioned, and a body SI1 integral withcollar 3|, the said body receiving the lower end of a tubular ,rod 32forming a telescopic arrangement with another 33. The upper end of rod32 is split and it is provided with a clamping screw 321. Rod 22 carriesasplit collar in whichv thereniay be clamped a rod 3d to which there isarticulated the curved plate 35 forming the abutment proper. A screw 331permits of clamping rod 34 .at the desired position.

Collar 3| is angularly fixed on member 3g'by means of ratchet teeth cutin collar @Gand engaged by a pawl, not illustrated, pressed by a springand freed by a hand lever iii?. lt will readily be grasped that bylifting lever SI2 the pavvl is disengaged from the ratchet and collar 3Qis free to'rotate.

There is associated with the table described an X-ray support comprisinga carriage 35 supported by castor' wheels and provided with broachesland 31g by means of which it may be xed to the base I of the tablethrough sockets (notshown) provided on the same. rlhis carriage supportstwo uprights 39d and. 39g connected by a cross-.bar 39. Uprights 39dand'39g slidably support sleeves (lo and dilo, each carrying anothersleeve All and Mg respectively, with their axes horizontal.driventhrough sleeves ll and'tllg; they are preferably-square incross-section, as well as the corresponding sleeves themselves, and theyare Pulleys 48d and 48g are varranged at the upper end of uprights 39dand 39g on the same trans'- verse shaft 48. The lower end of saiduprights also comprises pulleys 49g and 49 and the said pulleys receivetwo endless wires or strings 49g and 49d attached to noses 50 and 50gcarried by sleeves 40 and 40g. Counterweights 5I and 51g are provided tobalance the weight of the parts associated with the sleeves.

The carriage also supports theelectrcal apparatus 52 supplying currentto the X-ray bulb, and it is provided with a column 53 with anarticulated handle 54 by means of which the carriage may be moved.

It will easily be grasped that the carriage thus established permits ofplacing the X-ray bulb and the corresponding frame at any position. Fig.13 shows by way'of example in dash and dot lines the positioncorresponding to an X-ray eX- posure with the bulb under the body.
